Wont power up

[SarcasticElder]

Worked fine up until I woke up this morning when I tried to turn it on. I push the power button, everything starts to boot as normal, but only for a second or two, then everything stops and goes back to like I never hit the power button in the first place.

x99 aii MB

6800k (not overclocked)

evga 750 Plat power supply

evga ftw 1080

16GB gskill 3000 (already tried reseating it)

H115i all in one

 

No warning lights or beeps either.

No one has any ideas?

Well, this could be anything. Have you already tried any form of Troubleshooting?

 

Since you are running out of power my n1 guess would be a broken Power Supply so if you could replace that with another one this would be helpful.

If that´s not an option I suggest to open the case and have a look at all the connectors to make sure they are all where they should be (Hopefully plugged in).

 

Also, Unmount your GPU and try powering up your Computer with the onboard Video Card from the Motherboard.

 

After that report back so we can narrow it down further.

You want to reseat your CPU cooler too and apply new thermal paste.

If a CPU is overheating, your computer does exactly what you're describing.

 

This could be a number of things of course, but that's the one I'd check first because it's the one that poses the most risk if not taken care of.
